Isikimu ezinikeza izitshalo ukuze izilwane nabantu. Biology for Children

Kuleli phephandaba, isikimu kuzoxoxwa: ezivumela izitshalo nezilwane ukuba indoda. Ngaphandle abazalwane oluhlaza ukuphila kwethu Emhlabeni ngeke kwenzeke nhlobo. Siqine sibe kudingekile kakhulu - i-oksijini. Ngaphandle umoya wokuphila akunakwenzeka, ngisho izinhlanzi ngaphansi kwamanzi kwezimila kukhona nje umphumela we-photosynthesis.

Ngaphezu kwalokho, izilwane eziningi bazidle futhi njengoba umthombo wamanzi. uhlelo yethu: anika izitshalo ukuze izilwane nabantu, ngeke sikwazi ukuthwala zonke izakhi ezisetshenziswa izitshalo ngesikhathi kabusha i-oksijini.

Kuyadingeka ukuba akhulume ngomunye Eqinisweni: nakuba izitshalo akhiqiza i-oksijini, kodwa namanje futhi yisikhonyane. Inani ukukhiqiza kunalelo ukusetshenziswa, ukuze asebenzise ngaphezulu futhi thina kuthanda. Kodwa kabanzi mayelana okuzoxoxwa kamuva.

umoya

Kwethulwa kule scheme kwesigaba ezinikeza izitshalo nezilwane ukuba indoda, sikhombisa igesi inqubo ukukhiqizwa kabusha siphefumula zonke izidalwa eziphilayo eplanethini yethu. Le nqubo ibizwa ngokuthi i-photosynthesis biology. Ake sibheke lokhu kwenzeka kanjani.

Isikimu ethulwa ezinikeza izitshalo nezilwane ukuba indoda, ebonisa ukuthi inqubo ye-photosynthesis empeleni lukhuni. Ake sibheke-ke kwenzeka kanjani:

• isitshalo uthatha amanzi enhlabathini;
• ekhethekile izidakamizwa chlorophyll nokukhanya kwelanga usizo inqubo ye-photosynthesis;
• simila ithola amandla adingekayo;
• Ukusingathwa inqubo ye-photosynthesis (i-oksijini) adedelwa imvelo.

Kulokhu okungenhla kuyacaca: photosynthesis has nje ezimbili plus saturation izitshalo amandla futhi ukuvunguza komoya-mpilo nokunonophala.

ukudla

Ngakho, lokho kunikeza izitshalo nezilwane nabantu? Ukushayela (Grade 3), esiye enikeziwe izithombe, lisibonisa ukuthi izilwane eziningi ezidla izimila eziluhlaza.

iplanethi yethu ine inqwaba ezidla uhlaza. Futhi bonke badle izingxenye ezahlukene ezitshalweni eziluhlaza. Lokhu kwenza kube nokwenzeka olwenzeka endaweni zinhlobo eziningi ezidla uhlaza ku leyo nsimu efanayo ngaphandle kokulwa sokudla. Ngokwesibonelo, abanye bangase ziklaba bese uqede emacembe nezitshalo ezokudabuka kwamanye amazwe, ezinye ngisho ukuthatha nasezindaweni eliphakeme kwezihlahla. Ngokwesibonelo, indlovu utshani uyakwazi kokubili pinching isiqu, futhi lifinyelela amaqabunga emithi, futhi izindlulamithi ngenxa yini intamo yalo ende zingadla amashidi ahlelwe uchonywe. Lokhu kuvumela idatha ku izilwane abahlala kuyo leyo nsimu efanayo ngaphandle kokuncintisana sokudla.
